Hi All,

I'm running into a strange error. I recently decided to reprocess some of the data (180 volume bold files). I used orientLAS and 3dretroicor and then loaded the files into CONN where I ran functional Realign and Unwarp, functional center to (0,0,0) coordinates, and functional outlier detection. The resulting files (with the u* prefix) have the first volume normal, but volumes 2 - 180 are AP flipped. 

Any suggestions? I could probably just flip the last 179 volumes, but I'm concerned about why this is happening and the implications it has on the preprocessing. 

Best,
- Harris
